Synthesis and biological evaluation of 4,4-dimethyl-5,5-di(1- methylethyl)-2,3,4,5-tetrahydro-1H-dipyrrolo[3,4-d:2,1-f] [1,2]azasiline-1,3- dione and other pyrrolediones as new antibacterial active agents

The UV-light induced photosubstitution of 3,4-dibromo-2,5-dihydro-1H- 2,5-pyrroledione (2) [1] with pyrrole derivatives leads to 3-mono- and 3,4- disubstituted pyrrolediones depending on the starting material. These pyrrole homologues of arcyriarubin A (1) are further processed by nucleophilic substitution of the remaining bromine substituent with pyrrolidine. Cleavage of the protecting group affords the free pyrrole substituents. By UV-light irradiation the azasiline, system (6) is accessible, and its structure was established by X-ray methods. The in vitro antibacterial activity of the pyrrolediones was evaluated, and a strong activity of the compounds 4, 7, 8 and 12 against the methicillin- and ciprofloxacin-resistant bacterium Staphylococcus aureus 134/94 was established.

Compounds containing a michael-acceptor, especially maleimide or maleic acid derivatives, directly or indirectly linked to a chromophore and their use in long lasting sunscreen compositions

The present invention relates to compounds which are useful as sunscreens. The compounds persist on the skin for much longer than conventional sunscreens because they comprise a Michael acceptor linked directly or indirectly to a chromophore. The Michael acceptor is capable of undergoing a conjugate addition reaction with thiol groups present in cysteine residues of keratin and thus the compound is chemically bound to the skin and will not be removed by immersion in water.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 17057-04-4

Corydalis bungeana Turcz. attenuates LPS-induced inflammatory responses via the suppression of NF-kappaB signaling pathway in vitro and in vivo

Ethnopharmacological relevance Corydalis bungeana Turcz. (C. bungeana) is one of traditionally used medicines in China and possesses various biological effects, such as anti-inflammatory, antibacterial activity and inhibition of the immune function of the host. Aim of the study we studied the anti-inflammatory effect and molecular mechanism involved of C. bungeana both in vitro and in vivo model system in which the inflammatory response was induced by LPS treatment. Materials and methods Anti-inflammatory activity of C. bungeana was investigated by LPS-induced RAW 264.7 macrophages and BALB/c mice. The production and expression of pro-inflammatory cytokines were evaluated by Griess reagent, ELISA kits and RT-qPCR, respectively. Phosphorylation status of IkappaBalpha and p65 was illustrated by western blot assay. Results C. bungeana reduced the secretion of NO, TNF-alpha, IL-6 and IL-1beta through inhibiting the protein expression of iNOS, TNF-alpha, IL-6 and IL-1beta in vitro and in vivo. Western blot analysis suggested that C. bungeana supressed NF-kappaB activation via regulating the phosphorylation of IkappaBalpha and p65. Immunohistochemical assay also demostrated the histological inflammatory change in liver tissue. Conclusions The results indicate that C. bungeana supresses the activation of NF-kappaB signaling pathway through inhibiting phosphorylation of IkappaBalpha and p65, which results in good anti-inflammatory effect. In addition, C. bungeana attenuates inflammatory reaction by supressing the expression of various inflammatory cytokines both in vivo and in vitro.

Modulatory Effect of Chelidonium majus Extract and Its Alkaloids on LPS?Stimulated Cytokine Secretion in Human Neutrophils

Due to certain differences in terms of molecular structure, isoquinoline alkaloids from Chelidonium majus engage in various biological activities. Apart from their well-documented antimicrobial potential, some phenanthridine and protoberberine derivatives as well as C. majus extract present with anti-inflammatory and cytotoxic effects. In this study, the LC?MS/MS method was used to determine alkaloids, phenolic acids, carboxylic acids, and hydroxybenzoic acids. We investigated five individually tested alkaloids (coptisine, berberine, chelidonine, chelerythrine, and sanguinarine) as well as C. majus root extract for their effect on the secretion of IL-1beta, IL-8, and TNF-alpha in human polymorphonuclear leukocytes (neutrophils). Berberine, chelidonine, and chelerythrine significantly decreased the secretion of TNF-alpha in a concentration-dependent manner. Sanguinarine was found to be the most potent inhibitor of IL-1beta secretion. However, the overproduction of IL-8 and TNF-alpha and a high cytotoxicity for these compounds were observed. Coptisine was highly cytotoxic and slightly decreased the secretion of the studied cytokines. The extract (1.25?12.5 mug/mL) increased cytokine secretion in a concentration-dependent manner, but an increase in cytotoxicity was also noted. The alkaloids were active at very low concentrations (0.625?2.5 muM), but their potential cytotoxic effects, except for chelidonine and chelerythrine, should not be ignored.

Toward Transition Metal-Catalyzed Carbonylation of Methanol without HI as Copromoter: Catalytic Exocyclic Carbonylation of Cycloimino Esters

(Formula presented). Initial studies of a rare exocyclic C-O bond carbonylation are reported. Under the catalysis of Co2(CO) 8 in the absence of HI as the copromoter, cycloimino esters are carbonylated to afford N-acyllactams in high yields under relatively mild conditions (100-160C and 200-1000 psi). The reaction is interesting because it opens up the possibility of carbonylation of alcohols in the absence of HI.

Optimization of the N-lost drugs melphalan and bendamustine: Synthesis and cytotoxicity of a new set of dendrimer-drug conjugates as tumor therapeutic agents

Bendamustine and melphalan are very promising alkylating drugs with applicability in the treatment of various tumoral diseases, e.g., chronic lymphocytic leukemia (CLL) or breast cancer. However, numerous adverse effects limited their use. Therefore, 1,3,5-tris(3-aminopropyl)benzene (G0) and its G1 analogue 3,5-bis(3-aminopropyl)-N-(3-{3,5-bis[3-{3,5-bis(3-aminopropyl) benzoylamino}propyl]phenyl}propyl)benzamide were selected to design cytostatic drug-dendrimer conjugates to achieve tumor cell accumulation by endocytosis as already demonstrated for platinum complexes. The dendrimers act as carriers and an N-(2-hydroxyethyl)maleimide spacer between drug and carrier should guarantee a selective release of the cytostatics in the tumor cells. The resulting cytotoxicity was determined in vitro using the human MCF-7 and MDA-MB-231 breast cancer cell lines. It was demonstrated that melphalan caused cytotoxic effects depending on its free amino group (Boc protection strongly decreased the activity) but independent of a derivation of the carboxylic group (dendrimers and spacer binding). Esterification of bendamustine with the N-(2-hydroxyethyl)maleimide spacer strongly increased the hydrolytic stability of the N-lost moiety, so antiproliferative effects were yet observed in vitro.

Experimental and theoretical studies on the rotational barrier of 1-acyl- and 1-alkoxycarbonyl-2-pyrrolines

The conformational equilibrium as a result of the N-carbonyl bond rotation of several N-acyl- and N-alkoxycarbonyl-2-pyrrolines have been studied. The equilibrium constants and the rotational barriers were determined by theoretical methods (AM1, PM3, HF/3-21G(*) and HF/6-31G*) and, experimentally, by dynamic NMR (coalescence temperature). The measured rotational barriers for enecarbamates were found to be ca. 16 kcal mol-1 in C6D6 or C6D5NO2, whereas slightly higher values were found for enamides in C6D5NO2. Contrary to enamides, the rotational barriers for enecarbamates were not affected by changes in the polarity of the solvent employed.

Synthesis and biological evaluation of pyrrolinic isosteres of rilmenidine. Discovery of cis-/trans-dicyclopropylmethyl-(4,5-dimethyl-4,5-dihydro-3H-pyrrol-2-yl)- amine (LNP 509), an I1 imidazoline receptor selective ligand with hypotensive activity

To find new compounds selective for purported I1 imidazoline receptors (I1Rs), over I2 imidazoline binding sites (I2BS) and alpha2-adrenoceptors (alpha2ARs), a series of pyrrolinic isosteres of rilmenidine has been prepared and their biological activity at I1Rs, I2BS, and alpha2ARs evaluated. This isosteric replacement provided us with compounds which still bound to I1Rs but not to I2BS nor to alpha2-ARs. A limited structure-affinity relationship was generated around the heterocyclic moiety of these ligands. One compound in this series, LNP 509 (1e) [cis-/trans-dicyclopropylmethyl-(4,5-dimethyl-4,5-dihydro-3H-pyrrol-2-yl) -amine], had no detectable affinity at alpha2ARs yet was capable of lowering blood pressure after central administration. These pyrrolinic analogues constitute a new chemical class of imidazoline related compounds with high selectivity for the I1Rs. They could be used as new tools in the study of I1Rs and in the conception of new centrally acting hypotensive drugs.
